Introducing Quality Score for Facebook: FB's Ad Relevance Score Determines Ad Cost & Placement


As of last month, Facebook advertisers see a new Relevance Score metric, a measure of your Facebook ad's effectiveness and the equivalent of Google's AdWords Quality Score, in their ad reporting dashboard. This new score is an important ad quality signal that will affect both your ad delivery and the cost you pay for your Facebook campaigns.

Facebook will use feedback from ad viewers to determine this score on a scale of 1 to 10, with 10 being the highest possible score.

How Does Facebook's Ad Relevance Score Work?

Both positive and negative ad feedback factor into the Relevance Score equation. Positive interactions might include video views, conversions and other factors, depending on the type of ad you're running. When people hide or report your ad, your Relevance Score will suffer.

Facebook promises that the score is updated on a continual basis, as people view and interact with your ads.

Not all ads will have a Relevance Score, though – ads with guaranteed delivery will not be affected.

Everyone else will see this new metric appearing in their ads reporting tools and in third-party API tools, as Facebook works through the global rollout.

What Does Facebook's Relevance Score Actually Do?

In their feature announcement, Facebook said the higher your Relevance Score, the lower your cost of ad delivery. They want to show users the most relevant ads possible, so they're giving you a reward for quality, relevant ads here, just like Google has always done. On the other hand, if your ads are poorly targeted or not resonating with your audience, expect to pay more for clicks and impressions from now on!

Advertisers will want to keep a close eye on Relevance Scores throughout the life of each campaign. If your scores are slipping, your ad delivery will suffer and costs will increase.

How to Use Facebook Ad Relevance Scores

Facebook cautions that you shouldn't use Relevance Score as the primary indicator of ad performance (which I think is total nonsense heh), but then Google says that about Quality Score, too. Clearly, they want to downplay its importance since they still want you to spend on poor quality ads, but believe me when I say the factor that determines your ad placement and cost is pretty damn important!

Before launching a full campaign, test out your ads with small audiences to see which combinations of creative and targeting produce the greatest Relevance Score. Other metrics still matter, of course – cost, conversion, and reach among them.

This one metric is going to be massively impactful, though. It plays a role in how often your ad will appear and whether it will appear at all. It will guide your CPC and CPM. I'm pretty crazy about AdWords Quality Score for these same reasons – you can't underestimate the power of this score.

Remember, too, that bids still matter. On Facebook, ads with low Relevance Score but a high bid might still beat out the ad with the high RS and lower bid - I'll be busy reverse engineering the exact formula in the next few weeks.

I had a campaign where the click through rate was pretty high: 5.45% with very low cpc - my lowest cpc was .03. Yet the relevancy score was only 6. I guess if I can build the score up to 8 I'll probably get some free clicks.

So what are your thoughts on this scenario? We are currently running a campaign that has a relevancy score of 10, High positive rating, clicks are costing anywhere from .08-.10 ... but here's the kicker ... our negative rating is High too!!?? And the worst part ... when I pull up the page post insights I can't find any negative actions reported on any of the ads with a high negative rating. Our CTR hovers around 3.5%. It just doesn't make any sense. All I know is I have a profitable campaign that is converting at about 150% ROI, and I can't scale the thing because Facebook is likely to shut down the ad account if we put any money behind our ads with the high negative ratings. Any insight on this? Any advice? Anyone else have this problem too?

Thank you for any insight you can give here. We're stumped!

I have the same problem. Ad Relevance Score 7 : Positive Feedback - High, Negative Feedback - High. I search about this for days and no one seems to know a solution, there are just speculations but true is with ads running in high negative background we are in "red zone". It's only matter of time before the worst :(
